This work around doesn't really work - (upon recalc, sometimes the route is entirely different with a whole new set of impossible and/or illegal turns.) School buses must approach stops to starboard, cannot back onto certain roads for U-turns, etc. Suggest thinking about a product enhancement for a future release. Perhaps a right-mouse click to insert a 'Zero Service time' turn point, locked to before/after route-point sequence. These 'forced waypoints' would be erased when/if a route re-calc was initiated, but would be included in the output when a route plan was completed.
A friend who routes beer delivery trucks (and who suggested I investigate RouteXL) has similar needs to micro control turns and approaches.
Absent this enhancement, I cannot recommend RouteXL to our clients (Bus Companies and School Districts.)
